' tain new and useful Improvements in Combined Saw Sets and Swages; andI do doclare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in combined saw sets and swages.

One object of the invention is to provide a tool of this character bymeans of which a saw tooth may be swaged, set and channeled at the sametime or in one operation.

Another object is to provide a combined saw set and swage which will besimple,

strong, durable and inexpensive in construction, efiicient and reliablein operation and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a side view Fig. 2 is avertical longitudinal section showing the device applied to the tooth ofa saw; Fig. 3 is a bottom plan view; Fig. 4 is a detail view of theanvil removed from the body of the tool.

My improved saw 'swage and set comprises a body portion 1 which may beof any suitable size and shape, the same being here shown as preferablyof cylindrical form and is provided on one end with a head 2 which isalso preferably of cylindrical form and has in its outer end a circularsocket 3, the outer end of which is flared or has its sides curvedoutwardly to meet the outer side of the head 2 as shown at 4. Formedtransversely through the head 2 adjacent to the inner end of the socket3 and intersecting said end of the socket is a transverse slot 5 thepurpose of which will be hereinafter described.

Adapted to be engaged with and securely held in the socket 3 is acylindrical anvil 6 the inner end of which is reduced to form acylindrical shank 7 which is driven into the socket 3 and fits the samesufficiently tight to hold the anvil in operative position. The reducedportion of the anvil extends into the flared outer end 4 of the socketto a suitable extent to form between the curved annular walls of saidflared end and the outer surface of this portion of the anvil, a taperedannular recess 8 to receive the saw teeth when the tool is appliedthereto.

In operation the tool is engaged with the saw teeth in the manner shownin the drawing and the outer end of the body 1 is struck with suflicientforce by a hammer or other tool, thus forcing the recess 8 between theanvil and the flared outer end of the socket 3 of the set down onto thetooth, which operation will simultaneously set, swage, and channel thetooth. The channel in the tooth is produced by the annular or curvedsurface of the flared outer end of the socket 3 and the coactingcylindrical surface of the shank 7 of the anvil, these curved surfacesslightly bending the point of the tooth, when forcibly engaged therewithand thus forming the channel therein. In order to permit the anvil 6 tobe readily removed from the socket 3 when the anvil has become worn orfor any other reason, a wedge shaped instrument of any suitablecharacter is driven into the slot 5 and into engagement with the innerend of the shank 7 of the anvil, thus forcing the latter out of thesocket.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed. Havingthus described my invention, what I claim is:

A combined saw swage and set comprising a body portion having on one enda ofsaid socket, whereby when the tool is apset my hand in presence oftwo subscribing plied to the teeth of the saw for the purpose Witnesses.of swaging and setting the same, the annular Walls of the socket and theshank of the v THOMAS WILSQN' anvil Will simultaneously form channels inWVitnesses:

the teeth. v S. LLOYD WILsoN,

In testimony whereof I have hereunto S. A. WILSON.
